It’s very easy to add Common Ninja’s HTML code to Blogger.
1. First, copy the app’s HTML code. To do so, in the app’s dashboard, go to “Add to Website”. Here, click on the green button (it will automatically copy the code).
2. Sign in to blogger. Choose the blog you want to update. Then, in the left menu, click on “Theme”.
3. Under “My theme”, click more and select the “Edit HTML”. Paste the code you’ve copied before and click “Save”. That’s it. You should see Common Ninja’s app on your page.
